Today we will see a typical brute
stack flow applied to LSU Line 04 from the Livingston area at the Puchi
site:

NAME of sub-flow

Purpose

viewSEGY_1.82.gl

Display SEGY data for quality control

seg2sfam_182.gl

Convert SEGY data to OmegaSPS internal format

viewSfam_182.gl

Display OmegaSPS data set

trdelrev_182.gl

Delete and reverse polarity of traces

TraceHdrMth_182.gl

Changes station numbers for detectors (geophones) in the
trace headers

SPXY2Hdr_182.gl

Transfer shotpoint locations (UTM, Z=15) from an
editable text file to the trace headers in the seismic data set

DtectXY2Hdr182.gl

Transfer geophone locations (UTM, Z=15) to the trace
headers in the seismic data set

Cre8Frstgdb_182.gl

Create an initial geometry data base

mkCDPInGDB_182.gl

Create CDP geometry information in the data base and
pass it on to the seismic data headers

TraceMth_SrcDtct_Dist_182.gl

Create the shot-geophone (source_to_detector_distance)
in the headers of the seismic data by mathematical manipulation

viewCMP_182.gl

Check to see if the CMP's look all right

VelGenerator_182.gl

Create a velocity file

brutestack_182.gl

Generate the first pass stack by sorting the data in
CMP's then applying a hyperbolic NMO, filter, gain and summation.

As you process your own data set for your
course project you can start by using the above flows. Then you can
branch out and try new options in the flow. For example you may want to
change the velocity structure, apply an f-k filter, test different bin sizes
in your CMP geometry. (The image with the most usable geological
information wins!)
